Hello
I need help with setup wallpad using modbus:
google drive with manual:
https://drive.google.com/drive/folders/1...drive_link

i have some errors, code from ai

[17:49:15.467][D][modbus_controller:039]: Modbus command to device=2 register=0x100B no response received - removed from send queue [17:49:15.705][W][modbus_controller:284]: Duplicate modbus command found: type=0x4 address=4107 count=1 

any user tryed this wall pad?

I have 4 KC868-E16P-V2.3 with firmware version 2.2.14, after about one week, they go offline, no TUYA access(TUYA show Offline), and there is no Web-access. I have to power off/on to make them come online. It's random witch controller who goes offline, but all of them goes offline during one week or so.
They are powered by a MeanWell 12V 2.5A DIN-rail powersupply.

Hello

What is the suitable power supply voltage for KC868-16 - is the 13,5 V ok as well? Whats the minimum?

Hey there, 

some feedback and problems we detected on two N30 devices.

• Flash Guide with ESP Download Tool is incomplete, the guideline let you think to use the KCS bin file only. This is not correct, you will need more files (partion etc) to be able to flash.
  ESPHome Webflasher is the solution as it also accept the KCS Firmware File.
  

• EnergyConsumption in kWh seems to be not working in KCS Firmware (major bug!) Same problem as in Link
  

• Voltage Calibration is not possible in KCS Firmware
  
  
• Are negative power readings possible? 
  

• If yes, can there be an independent energy calculation per input for positive/negative consumption readings?
  

Hello,
I am looking for a KinCony solution for a professional home lighting automation setup.
Requirements:

• 16-channel relay controller (220V AC)
  
• Use of standard mechanical wall switches (2-way / 3-way)
  
• Real light state feedback (Home Assistant must always know ON/OFF state, even when switched manually)
  
• Mandatory Home Assistant integration (MQTT / ESPHome / native)
  
• Minimal GPIO usage (no one-GPIO-per-switch design)
  

1. Which KinCony model(s) do you recommend?
   
2. How is state feedback implemented (dry contact, relay feedback, current sensing, etc.)?
   
3. Do you have wiring diagrams or documentation for this scenario?

The DO1 output physically shows a high state. After uploading new software, when logging in directly to the controller, the inputs and outputs are disabled, but DO1 physically remains on all the time. I have no idea what is causing this. I haven’t connected any relays to the outputs yet.

Hello, I recently received an N20. I have access to it via Ethernet, but I can't connect it to "kinconyn20.local" nor can I connect it to Home Assistant. The strange thing is that it connects via MQTT from Home Assistant.

As soon as the device arrived, I flashed it to version v3 3.18.0. Its IP address is 192.168.3.78 (within my network range, OK), and its Wi-Fi access point is 192.168.4.1.

Is the problem that it can't access "kinconyn20.local"? Why doesn't Home Assistant recognize it?

I need to check the configuration of the CT clamps, as well as the L1 and L2 power inputs, which are not appearing.

I'm Spanish, sorry for the autotranslated English.

Hello Admin,

Have you ever created an example Arduino program to get results from API calls (HTTP/HTTPS Web Server)?
Btw, I used Kincony F16 ESPS3 with Tuya. 
And I have already tested mostly features in the KCS V3 firmware.

Thank you very much.

I have a Kincony A16v3, with Home Assistant running on a Pi4.

I ran a Momentary Push Button Switch to a switch input on the A16v3.  I set up an automation where you press the switch, and it runs an automation.

Is there a way to run a different automation on the way you press the switch?  Like, if I hold the button down, it triggers a different automation?

If this exists, can you point me toward a tutorial?

Thank you

Hello,
I am a new user of the Kincony A16. I would like to replace my current ESP32 with the A16, but I am having an issue with the relay modules. In my existing project, the relays are controlled using 3.3 V logic. How can I control a low-voltage relay module using the A16? Are there any available options or recommended solutions?
